Subject: [PATCH v3] arm64/mm: add fallback option to allocate virtually contiguous memory
Date: Mon, 12 Oct 2020 16:05:57 -0700	[thread overview]
Message-ID: <cover.1602542734.git.sudaraja@codeaurora.org> (raw)

V1: The initial patch used the approach to abort at the first instance of PMD_SIZE
allocation failure, unmaps all previously mapped sections using vmemmap_free
and maps the entire request with vmemmap_populate_basepages to allocate 
virtually contiguous memory.
https://lkml.org/lkml/2020/9/10/66

V2: Allocates virtually contiguous memory only for sections that failed
PMD_SIZE allocation, and continous to allocate physically contiguous
memory for other sections.
https://lkml.org/lkml/2020/9/30/1489

V3: Addressed trivial review comments. Pass in altmap to vmemmap_populate_basepages.
